Real‐Time and Rapid Dynamic Missile Identification Utilizing a TiOx Memristor Array
Advanced Intelligent Systems, EarlyView.Real‐time missile target identification is demonstrated using an artificial intelligence model based on step‐weighted long–short‐term memory networks and a TiOx memristor array. The approach classifies five projectile types with enhanced early‐stage prediction through data augmentation and custom training strategies. Achieving 94.4% accuracy, the model
